Even if you’re not a serious techie, you are probably familiar with IP addresses, for example, 192.168.1.1. It’s the address of a computer on a network, usually, the Internet. The only problem is as a result of the way the addresses are constructed, there are a relatively small number of them, and on the Internet we’ve essentially run out. To solve this problem, the powers that be have created a successor. The original addresses follow the IPv4, version 4, addressing scheme. The addresses of the successor, IPv6, version 6, designed to provide a virtually limitless supply, look very different, for example, 2001:0db8:85a3:0000:0000:8a2e:0370:7334. While we as users don’t typically need to handle these addresses directly, a service called DNS, domain name service, generally takes care of this, it is sometimes useful to work with them directly. Think back to my example IPv4 address. Can you easily memorize and work with it? Now trying memorizing and working with the IPv6 address. Obviously, we can’t. It’s ridiculous. I have no idea why the powers that decided to make IPv6 human-unusable, but they did, and it qualifies as an A to B violation.
